Abstract

From the fruits of Asparagus falcatus a novel minor (Z)-carotenoid has been isolated and, on the basis of spectral data interpretation, characterized as (9Z)-capsanthin-5,6-epoxide [(9Z,3S,5R,6S,3'S,5'R)-5,6-epoxy-3,3'-dihydroxy-5,6-dihydro-beta,kappa-caroten-6'-one, (1)]. In addition, seven other (Z)-carotenoids [namely, (9Z)-, (9'Z)-, (13Z)-, and (13'Z)-capsanthins, (9Z)- and (13Z)-capsorubins, and (9Z)-violaxanthin], which have been previously described from other plants, were isolated and identified.

摘要

从镰叶天门冬果实中分离出一种新型次要（Z）-类胡萝卜素，并基于光谱数据解释将其鉴定为（9Z）-辣椒红素-5,6-环氧化物[（9Z,3S,5R,6S,3'S,5'R）-5,6-环氧-3,3'-二羟基-5,6-二氢-β,κ-胡萝卜素-6'-酮，（1）]。此外，还分离并鉴定出了其他七种先前已在其他植物中描述过的（Z）-类胡萝卜素[即（9Z）-、（9'Z）-、（13Z）-和（13'Z）-辣椒红素、（9Z）-和（13Z）-辣椒玉红素以及（9Z）-紫黄质]。
